Abstract

Provided is an animal litter that is less liable to scatter and in which the depth of the solids is less liable to increase when a liquid such as urine has been absorbed. An animal litter composed of a plurality of particulates having water absorbency, wherein the particulates contain: long grains having a granularity of 4 mm or more and less than 10 mm, and a length that is greater than the diameter; and short grains having a granularity of 4 mm or more and less than 10 mm, and a length that is no more than the diameter. The long grains are provided with a core part primarily composed of pulp, and a coating layer containing highly water-absorbent resin and used for coating the core part. The weight ratio of the short grains in total of the long grains and the short grains is 10%-50%, inclusive.
